The LPC1764FBD100K: 128 KB Flash and 32 KB SRAM support a TCP/IP stack with CANopen or Modbus application, plus bootloader and diagnostics.
Supply range 2.4 V to 3.6 V. Internal oscillator saves a crystal for non-critical clocking.
Standard lead times apply and last-time-buy planning is not needed now.
The ARM Cortex-M3 core runs at 100 MHz, which is the maximum clock for this part. That speed supports real-time Ethernet frame processing and motor-control PWM update rates without external accelerators.
It integrates Ethernet MAC, CAN 2.0B, USB OTG, multiple SPI/I²C/UART, plus I²S audio and motor-control PWM — enough for a single-chip industrial gateway or drive controller.
